Coin packaging apparatus

ABSTRACT

A plurality of, usually three, wrapping rolls are arranged annularly in parallel, spaced relationship to receive a neat stack of coins in a central position therebetween and to wind a strip of wrapper around the circumference of the coin stack as it is caused frictionally to rotate by the wrapping rolls. For simultaneously moving these wrapping rolls toward and away from the central point therebetween, an arm rotatably supported at one end thereof is connected to the wrapping rolls by linkage means such that each of the wrapping rolls is thereby caused to move a distance determined by the angle of rotation of the arm. This arm is operated by first and second cam means in such a fashion that the wrapping rolls are first caused to move from their most spaced-apart to intermediate positions over a variable distance in accordance with the kind (diameter) of the coins of the stack to be packaged and, as this stack is placed in the central position therebetween, to their least spaced-apart positions over a predetermined distance, thereby tightly holding the stack for the succeeding packaging operation.

More specifically, the invention is directedto improvements in a coin packaging apparatus of the type comprisingmeans for arranging a prescribed number of coins of the samedenomination into a neat stack and a plurality of rotatable wrappingrolls arranged annularly in parallel spaced relationship to each other.Each time the stack of coins is carried to a central position betweenthe wrapping rolls, these rolls are displaced sideways intocircumferential contact with the stack of coins and are then set inrotation therewith to wind a strip of wrapper around its cir cumference.The lateral edges of the thus wound wrapper strip, still projectingbeyond the ends of the stack of coins, are fold-crimped as by apair offolding hooks for completely packaging the coins.

According to the prior art coin packaging apparatus of the typedescribed. each stack of coins to be packaged is carried to the centralpositon between the wrapping rolls while they are located in theirpredetermined most spaced-apart positions regardless of the diameter ofthe coins, and the wrapping rolls are successively moved intocircumferential contact with the stack of coins. Thus, in case the coinsto be packaged are of considerably smaller diameter than those of thedenominations to be ordinarily handled by the apparatus, the stack ofsuch coins may become disarranged in the central position between thewrapping rolls before the rolls are moved into contact therewith fromtheir most spaced-apart positions.

Further, according to the prior art coin packaging apparatus, thewrapping rolls are forced with constant force into contact with eachstack of coins from their predetermined most spaced-apart positionswithout regard to the diameter of the coins. It will therefore beapparent that the tightness with which the wrapping rolls hold the stackof coins therebetween is subject to change considerably depending uponthe diameter of the coins. This presents a serious problem especiallywhere coins of widely varying diameters must be handled by one and thesame apparatus, because a stack of coins when held too loosely or tootightly by the wrapping rolls cannot possibly be packaged in the correctmanner.

There is a further disadvantage with the prior art coin packagingapparatus in that when coins of a small diameter are to be packaged, thewrapping rolls are each required to travel an unnecessarily longdistance from the most spaced-apart positions into contact with thestack of such coins placed centrally therebetween, with the possibleresult that the coins may become upset in the meantime.

SUMMARY OF THE INVENTION In view of the listed disadvantages of theprior art, it is an object of this invention to provide an improved coinpackaging apparatus including a plurality of wrapping rolls which aremoved from their predetermined most spaced-apart positions tointermediate positions before each stack of coins to be packaged iscarried to a specified position therebetween and which are further movedfrom the intermediate to least spaced-apart positions. where thewrapping rolls are to come into circumferential contact with the stackof coins. only after the coins have actually been brought to thespecified position. The stack of coins can thus be securely held by thewrapping rolls with substantially no possibility of disarrangementbecause the wrapping rolls are required to travel a minimum distancefrom their intermediate to least spaced-apart positions.

Another object of the invention is to provide an apparatus, wherein theintermediate and least spacedapart positions of the wrapping rolls arevariable in accordance with the diameters of coins of variousdenominations to be handled by the apparatus. in such a manner that thewrapping rolls are required to travel an unvarying minimum distance fromtheir intermediate to least spaced-apart positions no matter whichdenomi nation of coins are to be packaged.

A further object of the invention is to provide an apparatus includingcam means for causing the motion of the wrapping rolls between theirmost spacedapart. intermediate and least spaced-apart positions, so thatno pressure is normally exerted on the wrapping rolls.

A further object of the invention is to provide an apparatus soconstructed that each stack of coins can be held by the wrapping rollsunder equally appropriate pressure regardless of their diameter.

With these objects in view and the other objects hereinafter set forth,this invention provides, in a coin packaging apparatus of the type abovestated, the improvement including an arm rotatably supported at one endthereof, and linkage means for connecting the arm at least to some ofthe wrapping rolls to translate the rotary motion of the former into thelinear motion of the latter toward and away from substantially thecentral axis between the wrapping rolls which are arranged annularly, insuch a manner that each of the wrapping rolls is caused to move adistance determined by the angle of rotation of the arm. The arm isoperated by first cam means adapted to cause the rotary motion of thearm through a variable angle in accordance with the diameter of thestack of coins to be packaged, and by second cam means adapted to causethe rotary mo tion of the arm through a predetermined angle regardlessof the diameter of the stack of coins. Hence, the wrapping rolls arefirst caused to move from their most spaced-apart to intermediatepositions over a variable distance determined in accordance with thediameter of the stack of coins and thence to their least spacedapartpositions over a predetermined distance regardless of the diameter ofthe stack of coins.

The features which are believed to be novel and characteristic of thisinvention are set forth with particularity in the appended claims. Theinventionitself, however, both as to its construction and mode ofoperation, together with the further objects and advantages thereof,will be best understood from the following description of a preferredembodiment thereof taken in connection with the accompanying drawings,wherein like reference characters denote like parts throughout theseveral views.

DETAILED DESCRIPTION As conducive to a full appreciation of the featuresand advantages of this invention, the general organization of a typicalcoin packaging apparatus to which the invention is directed will firstbe described. Referring therefore to FIG. 1, the illustrated coinpackaging apparatus 1 is broadly composed of a coin charging section 2through which coins to be packaged in neat stacks are introduced intothe apparatus, a coin stacking section 3 where each prescribed number ofthe coins are stacked up, a coin wrapping section 4 where each stack ofthe coins is packaged with a wrapper, a coin stack transferringmechanism 5 for directing each stack of the coins from the coin stackingsection 3 to the coin wrapping section 4, a wrapper supplying section 6for supplying the wrapper to the coin wrapping section 4, and a controlsection 7 for controlling the operation of the coin wrapping section 4.

More specifically, the coin charging section 2 includes a hopper 10through which the coins to be packaged are loaded onto a revolving disc12. As this disc 12 revolves at a suitable speed, the coins arecentrifugally sent out one by one into a linear passageway 11, FIG. 2,along which the successive coins are frictionally caused to advance bymeans of an endless belt 13. Also as indicated in FIG. 2, the passageway11 is provided with means 14 for sorting out those coins whose diameteris smaller than that of the coins of a preselected denomination.Counting means including a sprocket wheel 15 is further provided at theexit end of the passageway 11, the sprocket wheel 15 being caused torotate through a predetermined angle by each coin of the properdenomination traveling therepast. Hence, each time a predeterminednumber of coins are fed out of the exit end of the passageway 11, thesprocket wheel 15 is is temporarily rendered nonrotatable to prevent anyfurther coins from being fed out of the passageway.

Each predetermined number of coins thus delivered out of the passageway11 are directed through a chute 16 into a stacking cylinder 17 of theaforesaid coin stacking section 3, which section further comprises means18 for imparting vibrations to the stacking cylinder 17 to rearrange thecoins contained therein into a neat stack and shutter means 19 openablyclosing the bottom end of the stacking cylinder 17.

The coin wrapping section 4 comprises a plurality of (three in theillustrated example) wrapping rolls 20, 21, and 22 disposed verticallyin annular arrangement, and a pair of crimping hooks 23 and 24. Eachstack of coins delivered from the coin stacking section 3 in a mannerhereinafter set forth is placed vertically between these wrapping rolls,20, 21 and 22, whereupon all or some of the wrapping rolls are displacedhorizontally toward the stack of coins to hold the same tightlytherebetween. The stack of coins is further caused to rotate on its ownaxis as the wrapping rolls start winding a strip of wrapper 25 aroundits circumference.

As will be seen from FIGS. 1 and 2, the aforesaid coin guide mechanism 5is located below the shutter means 19 openably closing the bottom end ofthe stacking cylinder 17. The coin guide mechanism 5 includes avertically movable guide tube 28 having a flanged top 27 for guidingeach stack of coins from the stacking cylinder 17 down to the spacingbetween the wrapping rolls 20, and 22 as the bottom end of the stackingcylinder is opened by the action of a pair of arms 26 of the shuttermeans 19. A support rod 29 is telescopically received in the guide tube28 to support the stack of coins between the wrapping rolls 20 to 22. Aswill be seen from FIG. 1, the entire coin guide mechanism 5 swings outof vertical alignment with the coin wrapping section 4 each time thepackaged stack of coins is to be discharged therefrom.

The wrapper supplying section 6 comprises holding means 30 for holding aroll of the strip of wrapper 25, feed roll means 33 consisting of driveroll 31 and idler roll 32 which cooperate to feed out the strip ofwrapper 25, and cutter means 34 for cutting the strip of wrapper 25 intoa length sufficient to package the stack of coins held between thewrapping rolls 20 to 22. The reference numeral 8 in FIGS. 1 and 2designates a chute through which the packaged stack of coins is to bedispensed out of the apparatus.

A preferred embodiment of the invention will now be described withreference to FIG. 3 as adapted specifically for use in the coin wrappingapparatus of the above described general organization. It will be notedin FIG. 3 that bores formed in some parts are hatched, and those formedin other parts unhatched. This is to indicate the fact that the partshaving hatched bores are to be fixedly mounted on shafts or pinsreceived in such bores, and the parts having unhatched bores to berevolvably or loosely mounted on shafts or pins received in such bores.thereby facilitating the succeeding description of the preferredembodiment of the invention.

A knob 35 to be turned in accordance with the denomination of coins tobe packaged is coupled to a shaft 36 either directly or via a rotaryswitch, motor, cam or like means not shown in the drawing. A gear 37fixedly mounted on the shaft 36 is in mesh with a gear 39 looselymounted on a shaft 38, on which shaft is further securely mounted a cam40 adapted to determine the distances the wrapping rolls 20, 21 and 22are to be moved. As illustrated in more detail in FIG. 4, the cam 40 hasa stepped configuration on its circumference in accordance with thediameter of coins of various denominations to be packaged. Furtherfixedly mounted on the shaft 38 are arms 41 and 42 and a sector gear 43,and a shaft 44 loosely extends approximately centrally through the arm41. The shaft 44 also loosely extends approximately centrally through alever 45 to turnably support the same above the arm 41. The lever 45carries a roller 46 on one end thereof which is yieldably urged againstthe stepped circumference of the cam 40 as by a spring 47.

As seen in both FIGS. 3 and 4, cams 49 and 50 are fixedly mounted ashaft 48 which is caused to make one complete revolution for each cycleof wrapping operation. The cam 49 has formed on its circumference anarcuate edge 51 of a smaller radius adapted to cause the wrapping rolls20, 21, and 22 to be located in their least spaced-apart positions. andanother arcuate edge 52 of a greater radius adapted to cause thewrapping rolls to be located in their intermediate positions, ashereinafter set forth in further detail. The other cam has a protuberantcircumferential edge 53 adapted to cause the wrapping rolls 20, 21 and22 to be located in their most spaced-apart positions The cam 49 has itscircumference of the above configuration maintained in contact with aroller 54 mounted on the other end of the aforesaid lever 45, whereasthe cam 50 is to make contact only at its protuberant circumferentialedge 53 with a roller 55 mounted on the corresponding end of the arm 41.

The aforesaid sector gear 43 fixedly mounted on the shaft 38 is in meshwith another sector gear 57 similarly fixedly mounted on a shaft 56.Further mounted on this shaft 56 are arms 58, 59 and 60 and a gear 61,which gear is adapted to convey the rotation of a motor, not shown, tothe wrapping roll 20. The arms 58 and 59 are interconnected at theirrespective intermediate points by a pin or rod 62 extending verticallytherebetween, and the wrapping roll 20 is rotatably supported betweenthe free ends of the arms 58 and 59 via shafts 63 and 64 extendingaxially outwardly from both ends of the wrapping roll. A pinion 65mounted on the shaft 64 is in mesh with the gear 61 to receivetherethrough the rotation of the above mentioned motor.

The arm 42 on the shaft 38 has its free end turnably coupled to one endof a link 66 and further to a spring 67 capable of providing a constantload, and the other end of the link 66 is turnably coupled to one end ofan arm 69 the other end of which is secured to a shaft 68. Also fixedlymounted on this shaft 68 are a cooperative pair of arms 70 and 71rotatably supporting the wrapping roll 21 between the free ends thereofvia shafts 73 and 74 extending axially outwardly from both ends of thewrapping roll. A gear 72 loosely mounted on the shaft 68 is in mesh witha pinion 75 on the shaft 74 of the wrapping roll 21 via an intermediategear 77 loosely mounted on a shaft 76 extending vertically through thearms 70 and 71, so that the wrapping roll 21 is caused to rotate by thesame motor as the wrapping roll 20.

The arm 60 on the shaft 56 has its free end turnably coupled to one endof a link 78 the other end of which is turnably coupled to an arm 80fixedly mounted on a shaft 79. Further fixedly mounted on this shaft 79is a cooperative pair of arms 81 and 82, each substantially in the shapeof a C, rotatably supporting the Wrapping roll 22 between the free endsthereof via shafts 83 and 84 extending axially outwardly from both endsof the wrapping roll.

Proceeding to the description of this preferred embodiment of theinvention, the knob 35 is first turned selectively to a specifiedangular position in accor dance with the denomination, or diameter, ofthe coins to be packaged in order to preset the speed of the motor fordriving the wrapping rolls 20, 21, and 22 and the wrapper feed rolls 31and 32 at a value suitable for handling such coins. Since the shaft 36rotates with the turn of the knob 35, the cam 40 is caused to turn tothe desired angular position via the intermeshing gears 37 and 38. It isassumed that as illustrated in FIGv 7A, the roller 55 on the arm 41 isnow in contact with the protuberant circumferential edge 53 of the cam50 and,

therefore, that the roll 54 on the le er 45 is urged by the spring 47into contact with the arcuate edge 52 of the cam 49. Hence, the otherroll 46 on the lever 45 is held out of contact with the steppedcircumference of the cam 40, so that the wrapping rolls 20 to 21 areheld in their most spacedapart positions regardless of the diameter ofthe coins to be packaged, as indicated by the solid lines in FIGS. 5 and6.

As the shaft 48 turns counterclockwise, as vieved in FIG. 4, in stepwith the cams 49 and 50, with the relative angular positions of thesecams unchanged, the roller 55 on the arm 41 moves out of the protuberantcircumferential edge 53 of the cam 51) and thus becomes out of contactwith the cam 5-0, while the roller 54 on the lever 45 is still-held incontact with the arcuate edge 52 of the cam 49, as illustrated in FIG.73. it will be understood from FIG. 3 in particular that the lever 45 isnow pulled by the spring 47 in such a manner that the roller 46 thereoncomes into contact with the cam 40 at its desired circumferential pointWith this motion of the lever 45, the arm 41 is caused turn around theshaft 38 through an angle which is determined only by the distance thelever 45 moves until its roller 46 comes into contact with thecircumference of the cam 49.

The arm 42 and the sector gear 43 fixedly mounted on the shaft 38 arelikewise caused to rotate through a predetermined angle by the constantload spring 67. This rotation of the arm 42 around the shaft 38 resultsin the rotation of the shaft 68 through a corresponding angle via thelink 66 and the arm 69, so that the pair of arms 70 and 71 fixedlymounted on this shaft 68 are caused to turn correspondingly, therebycarrying the wrapping roll 21 a step closer to the central axis of theannularly arranged wrapping rolls 20, 21 and 22.

The rotation of the shaft 38 is further transmitted via the intermeshingsector gears 43 and 57 to the shaft 56, with the result that thewrapping roll 20 is caused to move a step closer to the central axis ofthe annularly arranged wrapping rolls 2t), 21 and 22 by the pair of arms58 and 59 secured to the shaft 56. Furthermore, the rotation of theshaft 56 is conveyed to the shaft 79 via the arm 60, the link 78 and thearm 80, and the pair of arms 81 and 82 secured to this shaft 79 causesthe wrapping roll 22 also to move a step closer to the central axis.

It is to be noted that the distances the wrapping rolls 20, 21 and 22are thus caused to'rnove toward. the axis therebetwecn are determined bythe working position of the stepped circumference of the cam 40 withwhich the roller 46 on the lever 45 comes into contact as previouslymentioned. Thus, in the case Where the stack of coins A to be packagedis of relatively small diameter as shown in FIG. 5, each of the wrappingrolls 20, 21 and 22 will move a distance d1 to the intermediate positionindicated by the lines consisting of alternating dashes and twoconsecutive dots. if the stack of coins A is of relatively largediameter as shown in FIG. 6, on the other hand, then each of thewrapping rolls will move a smaller distance d2 to the intermediateposition also indicated by the lines consisting of alternating dashesand two consecutive dots. This difference between the distances 411 andd2 arises from the corresponding difference of the working positions ofthe circumference of the cam 31 relative to the roller 46 on the lever45.

As all the wrapping rolls 20, 21, and 22 have moved to the intermediatepositions determined in accordance with the diameter of the coins to bepackaged as above stated, the guide tube 28 of the coin guide mechanismset forth in connection with FIG. 1 is caused to rise, as by means of acam mounted on the shaft 48, up to a position immediately below thebottom of the stacking cylinder 17 by passing through the central axisof the annularly arranged wrapping rolls 20, 21 and 22, as will be bestunderstood from FIG. 2. As the shutter means 19 succeedingly operates inaccordance with the prior art to open the bottom end of the stackingcylinder 17, the coins which have been arranged into a neat stacktherein are deposited by gravity on the guide tube 28, which isthencaused to descend to carry the stack of coins down to the centralposition between the wrapping rolls 20, 21, and 22.

Since the shaft 48 is in constant rotation with the cams 49 and 50 asaforesaid, the roller 54 on the lever 45 rides on the arcuate edge 51 ofthe cam 49 when the stack of coins has been brought down to the centralposition between the wrapping rolls 20, 21, and 22 in the abovedescribed manner. This state is illustrated in FIG. 7C. Then, as will beseen from the foregoing description, each of the wrapping rolls 20, 21and 22 is caused to move a predetermined distance 1 toward the centralaxis therebetween regardless of the diameter of the stack of coins A, asindicated by the dot-and-dash lines in FIGS. 5 and 6, so that the coinsare now held securely by the wrapping rolls. Since this motion of thewrapping rolls to their least spaced-apart positions is caused by thecam 49 only, it will be apparent that each wrapping roll moves thepredetermined distance I irrespective of the diameter of the coins to bepackaged.

As the stack of coins A becomes thus held securely between the wrappingrolls 20 to 22 as illustrated in FIG. 5 or 6, the guide tube 28 of thecoin stack transferring mechanism 5 is caused to swing sideways out ofalignment with the central axis of the wrapping rolls in accordance withthe prior art. The wrapping roll 20 is then set in rotation via the gear61 and the pinion 65, and the wrapping roll 21 is also simultaneouslyset in rotation via the gears 72, 77 and 75. The wrapper feed roll means33, comprising the drive roll 31 and the idler roll 32, also becomesoperative as rotation is imparted in a known manner to the drive roll31. The strip of wrapper with its loose end held between the feed rolls31 and 32 is thereby frictionally fed forwardly, and due to the tensionthus exerted, the strip of wrapper is cut into a suitable length by thecutter means 34. The piece of wrapper thus separated from the rest ofits continuous strip has then its leading end caught between one of thewrapping rolls 20, 21 and 22 and the stack of coins and is succeedinglywound around its circumference as these coins are caused to rotate ontheir axis by the wrapping rolls.

Upon complete winding of the wrapper piece around the circumference ofthe stack of coins, the pair of crimping hooks 23 and 24 shown in FIG.2, approach the upper and lower ends, respectively, of the stack ofcoins by the action of the cam, not shown, which may be mounted on theshaft 48. The folding hooks 23 and 24 operate to fold crimp the looselateral edges of the wrapper piece inwardly over both ends of the stackof coins and are then turned away therefrom by the action of the samecam.

As the packaging of the stack of coins is thus completed, the earns 49and 50 still rotate with the shaft 48 until the roller 54 on the lever45 rides again over the arcuate edge 52 of the cam 49, and the roller 55on the arm 41 over the protuberant circumferential edge 53 of the cam50. As a consequence, the wrapping rolls 20, 2l. and 22 are caused tomove back to their most spaced-apart positions in the manner previouslyset forth, so that the packaged stack of coins is released and falls bygravity into the chute 8 for dispensation out of the apparatus. Thus,one complete cycle of coin packaging operation comes to an end as theroller 55 on the arm 41 rides completely over the protuberantcircumferential edge 53 ofthe cam 50. The rotation of the motor issuspended pending the initiation of the next cycle of packagingoperation.

While in the above described embodiment of the invention, all thewrapping rolls 20 to 22 are made movable toward and away from thecentral axis therebetween, it is possible that at least one of thewrapping rolls be made stationary while the others are made movabletoward and away from the stationary wrapping roll. Moreover, thewrapping rolls 20 to 22 can be caused to move only between their mostspaced-apart and least spaced-apart positions instead of stopping overat the intermediate positions as in the foregoing disclosure. It is alsopossible that the distances the respective wrapping rolls are caused tomove from their most spaced-apart to intermediate or least spacedapartpositions be changed not for each denomination or diameter of coins tobe packaged but for each of several groups of coins of differentdenominations into which the coins are previously classified accordingto their diameters.

Thus, while the preferred embodiment herein disclosed is well calculatedto accomplish the objects above stated, it will be easy for thoseskilled in the art to devise many modifications, substitutions orchanges within their usual knowledge, and in some instances somefeatures of the invention may be employed without the corresponding useof other features. It is therefore appropriate that the invention beconstrued broadly and in a manner consistent with the spirit and scopeof the invention.
